#124132 - A path to GND would still be needed Responding to: ???'s previous message |
Oliver said:
Presumably the processor ground was effectively through the input clamping diodes, so the processor was running about 0.7V above the system ground. A rather low ohmic path from some port pin to GND would still be needed for this. Via connected voltmeter at P0? Kai |

| P0 not low enough (0.85V) | 01/01/70 00:00 | |

| Not useful? Overrated?? | 01/01/70 00:00 | |

| A path to GND would still be needed | 01/01/70 00:00 | |
| paths to GND might be fatal | 01/01/70 00:00 | |
| Thanks for the tip | 01/01/70 00:00 | |
| Rather low ohmic path | 01/01/70 00:00 | |
| thanks | 01/01/70 00:00 | |
| if that is so | 01/01/70 00:00 | |
| P0 - all's well | 01/01/70 00:00 | |
| Another Thanks | 01/01/70 00:00 | |
| Richard, I hope you are well now | 01/01/70 00:00 | |
| not necessarily for long | 01/01/70 00:00 | |
| Aware of that! | 01/01/70 00:00 | |
| Isn't this whole thing rather silly? | 01/01/70 00:00 | |
| good practice, Richard... | 01/01/70 00:00 | |
| Nooooooo... | 01/01/70 00:00 | |
| Newbies aren't rigorous! | 01/01/70 00:00 | |
| That\'s one place where we can help them! | 01/01/70 00:00 | |
| still glad I posted this one! | 01/01/70 00:00 | |
| it's maybe better | 01/01/70 00:00 | |
| It's a silly mistake, but one we've all made! | 01/01/70 00:00 | |
